And for that reason, these prejudices are the height of stupidity. To be racist or sexist* is to dehumanise oneself, not just your victim. It is to pretend that penises and dark skin, or vulvas and light skin (none of which are the seat of cognition) trump (or Trump) the content of one’s thinking.

(*As always, “sexism” refers not just to misogyny, but homophobia and transphobia as well.)
